"Weird Al" Yankovic

Alfred Matthew "Weird Al" Yankovic (born October 23, 1959) is an American singer-songwriter, musician, parodist, record producer, satirist, music video director, film producer, actor, and author. Yankovic is known for his humorous songs that make light of popular culture and often parody specific songs by contemporary musical acts.

"Weird Al" performs the song "Rabbitage" exclusively for American Dad! in "First, Do No Farm" after Stan and Roger debate the possibility of getting Weird Al to perform it. In the middle of the song, they get a rejection notice calling their idea 'stupid.'
